Oracle表空间扩容

查看表空间位置

SELECT tablespace_name, 
file_id, 
file_name, 
round(bytes / (1024 * 1024), 0) total_space 
FROM dba_data_files 
ORDER BY tablespace_name; 

system扩展表空间

alter database datafile '/u01/app/oracle/oradata/XE/system.dbf' autoextend on next 500M maxsize unlimited;

手动设置system表空间大小为9G

alter database datafile '/u01/app/oracle/oradata/XE/system.dbf' resize 9G;

增加system01表空间到system表空间不允许自动增长

alter tablespace system add datafile '/u01/app/oracle/oradata/XE/system1.dbf' size 10G autoextend off;
